What Is Kluyveromyces/Lactobacillus/Phaseolus Angularis Seed Oil Ferment Filtrate?
Kluyveromyces/Lactobacillus/Phaseolus Angularis Seed Oil Ferment Filtrate is a fermented extract made from adzuki bean seed oil. The process starts with pressing the small red beans of Phaseolus angularis to obtain their nutrient rich oil. This oil is then introduced to two friendly microorganisms, Kluyveromyces yeast and Lactobacillus bacteria. During fermentation these microbes break down large oil molecules into smaller ones, create new peptides and release antioxidants. Once the fermentation is complete the mixture is filtered to remove solids, leaving a clear liquid known as the ferment filtrate.
Fermented plant extracts gained popularity in Korean skincare where the search for gentle yet potent active ingredients led formulators to borrow techniques from traditional food fermentation. Brands noticed that fermentation can make oils lighter, boost antioxidant content and improve skin compatibility. Because of these benefits the adzuki bean oil ferment is now included in a variety of cosmetic products.
You will usually spot this ingredient in lightweight serums, hydrating essences, soothing masks, anti aging lotions, scalp tonics and shine boosting hair conditioners. Its mild nature allows it to blend well with both water based and oil based formulas, making it versatile for leave on products and rinse off treatments alike.
Kluyveromyces/Lactobacillus/Phaseolus Angularis Seed Oil Ferment Filtrate’s Cosmetic Benefits/Uses
This multitasking ferment brings several useful actions to a beauty formula
- Antioxidant: Helps neutralize free radicals generated by UV light and pollution which can otherwise speed up the look of aging and dull the skin or hair
- Astringent: Provides a mild tightening feel that can lessen the appearance of enlarged pores and give the skin a smoother finish
- Hair Conditioning: Coats the hair shaft with light nutrients enhancing softness shine and combability without weighing strands down
- Skin Conditioning: Supplies amino acids and sugars from fermentation that support the skin barrier improving hydration suppleness and overall comfort
Who Can Use Kluyveromyces/Lactobacillus/Phaseolus Angularis Seed Oil Ferment Filtrate
This ferment filtrate is generally suitable for all skin types. Its lightweight texture and mild astringent action make it helpful for normal, oily and combination skin while the added amino acids aid barrier support for dry or sensitive complexions. Because the ingredient is low in oil residue and sits lightly on the skin it tends to work well for those prone to clogged pores
The material is produced from adzuki bean oil and two food grade microorganisms with no animal derived components so it fits vegan and vegetarian preferences
No specific concerns have been raised regarding use during pregnancy or while breastfeeding. The ingredient is non systemic and used topically at low concentrations yet this is not medical advice. Expectant or nursing mothers should always review any skincare routine with a qualified healthcare provider
Kluyveromyces/Lactobacillus/Phaseolus Angularis Seed Oil Ferment Filtrate is not known to increase photosensitivity so it can be applied day or night without extra sun precautions beyond the daily SPF already recommended
Potential Side Effects/Adverse Reactions
Individual responses to topical Kluyveromyces/Lactobacillus/Phaseolus Angularis Seed Oil Ferment Filtrate vary. The points below outline potential issues although most users will not encounter them when the ingredient is properly formulated
- Temporary redness or warmth
- Mild stinging on compromised or freshly exfoliated skin
- Allergic contact dermatitis in people sensitive to legumes, yeast or ferment by-products
- Scalp or skin flaking if overused in very high concentrations
- Rare follicular irritation on extremely reactive skin
If you experience persistent discomfort or an unexpected reaction stop using the product and consult a healthcare professional
Comedogenic Rating
Rating: 1 / 5
The ferment filtrate contains mostly low–molecular-weight peptides, sugars and lightweight lipids produced during fermentation. These molecules spread easily and rinse away cleanly, so they are far less likely to lodge inside pores compared with heavier unfermented oils. The parent adzuki bean oil already sits on the lower end of the comedogenic scale and the additional breakdown that occurs during fermentation lowers that potential even further.
Because of this low score the ingredient is generally suitable for skin that tends to clog or break out.
As with any formulation, the overall pore-clogging risk will also depend on the other ingredients in the finished product and how thickly it is applied.
Summary
Kluyveromyces/Lactobacillus/Phaseolus Angularis Seed Oil Ferment Filtrate delivers four key actions: it helps neutralize free radicals for an antioxidant boost, gives a mild pore-tightening feel, conditions skin by supplying small peptides and sugars that support the barrier, and smooths the hair shaft for softness and shine. These benefits stem from the fermentation process which breaks down adzuki bean oil into more bio-available components and creates new skin-loving metabolites.
While it is not yet a household name it has gained steady traction in K-beauty inspired serums essences and scalp tonics thanks to its gentle multipurpose profile. Formulators appreciate its light texture and compatibility with both water and oil phases which makes it easy to slot into modern lightweight products.
Overall safety is considered high with irritation or sensitization reported only rarely. Still it is smart practice to patch test any new product that features this ferment especially if you have a history of sensitivities.
